Method for producing wound dressings on the basis of phospholipid-containing nanodispersions

A method for producing wound dressings on the basis of phospholipid-containing nanodispersions, comprising the following method steps:

• a) mixing at least one phospholipid with at least one pharmaceutically acceptable oil and water,
• b) performing an emulsification by rotor-stator or ultrasonic emulsification or by high-pressure homogenization of the mixture to obtain a dispersion, wherein at least 90% of the particle droplets have a diameter of less than 10 μm,
• c) mixing the dispersion with the aqueous solution of a pharmaceutically acceptable polymer,
• d) layered application of the resulting polymer solution with dispersed nanoparticles on a carrier,
• e) drying at an elevated temperature, reduced pressure, and/or freeze-drying,
• f) optionally mechanical separation of the layer and/or separation from the carrier.
